NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Aug. 1906.

Application filed May 10, 1906. Serial No. 316,187.

To all whom it may concern.- Be it known that 1, JOHN B. ZORN, a citizen of the United States, residing at Wisdom,

in the county ofBeaverhead and State of Montana, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do hereby declare the following to be a full, clear, and exact description of the reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in non-refillable. bottles; and the object of the invention is to produce a device of this nature comprising a stopper-casing having right and left spiral passage-ways in the upper portion thereof and a weighted and a float valve of light material, whereby when li uid is poured from the bottle the suction will cause the float-valve to unseat, and in an attempt to refill the bottle the light valve will float to a valve-seat above and the heavy valve will fall to a seat below, the pressure of air intermediate the valves holding the same seated.

The invention consists in various other details of construction and combinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure 1 is a vertical sectional view through my improved valve; and Fig. 2 is a detail view with parts broken away, showing the spiral Ways within the stopper.

Reference now being had to the details of the drawings by letter, A designates the neck of a bottle having an annular groove A formed in the inner surface thereof adapted to receive a locking-spring B. C designates the casing of the stopper, which may be of any suitable material, preferably glass, and is provided with an annular groove O adapted to register with said groove A, whereby said spring B may engage the registering grooves and hold the stopper within the neck of the bottle. Said stopper has a valve-seat D at the lower marginal edge of a chamber E, which latter is of spherical shape, and said valve-seat has a single cross-piece E, with openings on either side, whereby the liquid may freely flow out of the bottle when the valves are unseated. F designates a valve made, preferably, of metal or glass and is conical-shaped on its upper surface. H designates a valve-stem which is supported by the cross-piece E of said valve-seat and passes centrally through the valve F, which works freely thereon. valve-stem passes through an opening in the cross-piece K of the valve-seat K, and N designates a float-valve made, preferably, of cork or other light material and mounted to have a vertical movement upon said stem. The under surface of said float-valve N is chambered out, corresponding to the conical surface of the Weighted valve F, for the pur pose of allowing the two surfaces to fit snugly together, thereby creating a suction between the two, causing the valves to hold together while the liquid flows out through the neck of the bottle, and its upper surface is preferably The upper end of said flat and is adapted to contact against the seat K when the valve is at its farthest limit from the valve F.

Above the valve-seat K are arranged right and left spirals O and .0, respectively, which extend from a slight distance above the valve-seat K to a point near the outer end of the stopper-casing. Said spirals are formed for the purpose of preventing any tampering with the valves by inserting instruments of any kind for the purpose of holding the valves unseated'should an attempt be made to refill a bottle equipped with my improved stopper.

A suitable cover may be applied to the top of the neck.

In operation it is intended to fill a bottle equipped with my improved valve, after which the valve is inserted in place, and in the event of it being attempted to refill the bottle when the stopper is adjusted in the neck when liquid is poured in the stopper the light valve will float to the top and the heavy valve will lower to its seat. The pressure of air between the two valves will hold both tight to their seats, thus preventing any liquid'entering the bottle. When it is desired to empty liquid from the bottle, the in- From the foregoing it will thus be seen that while the spring engaging the registering grooves in the stoppercasing and neck of the bottle will effectually hold the stopper within the neck it will be impossible to remove the stopper Without breaking the neck of the bottle, thus surely preventing the refilling of the bottle by the removal of the stopper and afterward replacing the same.

What I claim is 1. In combination with the neckof a bottle, a stopper-casing, means for holding" the same within the neck of the bottle, said casing having two valve-seats at the top and bottom of 'a chambered portion therein and spiral passage ways between said chamber and one end of the casing, a weighted valve and a float-valve mounted in said chambered portion, and a stem upon which said valves are guided, as set forth.

2. In combination with the neck of a bottle, a stopper-casing, means for holding the same within the neck of the bottle, said casing having two valve-seats at the top and bottom of a chambered portion therein and spiral passage-ways between said chamber and one end of the casing, a stern supported between said valve-seats, a weighted valve movably mounted upon said stem and adapted to seat against the lower valve-seat, and a float-valve also mounted to move upon said stem and adapted to seat against the outer of s the two valve-seats, as set forth.

3. In combination with the neck of a bottle, a stopper-casing, means for holding the same within the neck of the bottle, said casing having two valve-seats at the top and bottom of a chambered portion therein and spiral passage-ways between said chamber and one end of the casing, a stem supported between said valve-seats, a weighted valve movably mounted upon said stem and adapted to seat against the lower valve-seat, and a float-valve also mounted to move upon said stem and adapted to seat againstthe outer of the two valve-seats, the outer face of said weighted valve having a conical surface and the inner surface of said float-valve a chainbered portion adapted to conform to said conical surface of the Weighted valve against which it is adapted to be held by suction as liquid is poured from the bottle, as set forth.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.

JOHN B. ZORN.
